OILING DEVICE.

Specification of Letters Patent.

Patented Mar. 23, 1915.

Appllca'don filed January 22, 1909, Serial No. 473,671. Renewed August21, 1914. Serial No. 857,949.

- T 0 all whom it may concern Be it known that I, J OHN W. BLOCK,citizen of the United States, residing at oliet, in the county of WVilland State of Ilhnols, have invented certain new and .useful Improvementsin an Oiling Device, of which the following is a specification.

This invention relates to improvements 1n means for applying lubricantsto vertically arranged shafts or spindles whereby the oil will becontinuously and automatically congravity, from an oil chamber orreceptacle.

The especial object of the improvements which form the subject matter ofthis application is to provide shaft lubricatingmeans which willpositively, automatically and effectively conduct the lubricant to thesurface of the bearings to be lubricated, against the action of gravity,and in which any excess of oil will be caught and returned to suchbearings without waste.

For the purpose of showing the principles involved in my invention andnot as a demonstration of a particular mechanical application thereof, Isubmit herewith a drawing illustrating one method of carrying out myinvention.

The figure represents in section an upright stationary shaft, carryingrotatable members and indicating one method of applyin my invention.

Referring to the details of the figure, 5 re resents a stationary baseor support in w ich is fixed an upright shaft 7. On the upper side ofthe base and surrounding the lower portion of the shaft is anoil-chamber or receptacle 6. Rotatably mounted on the shaft is a memberhaving a tubular extension or sleeve 8 which surrounds the shaft for thegreater part of its length and is in frictional contact therewith. Onthis sleeve is fixed a pulley 9 which may be driven by any suitablepower, the driving means'not being shown. The shaft has an axial bore 11the lower end of which communicates with the chamber 6 by a radial bore12, and

- the upper end of the bore 11 is open. Se-

cured to the member. 8 so as to rotate there with is a rod 10 havingmale helical threads thereon, said rod extending the full length of theaxial bore of the shaft 7, thereby serving when'the pulley is driven inthe or carried by the spiral rod against gravity to the upper end of theshaft where it will overflow the top of the shaft and down along thesides of the latter'thus lubricating the contiguous surfaces of shaftand sleeve.

The excess oil will drop into the chamber 6 v i to be used again in themanner indicated. ducted to the bearing, against the force of I am awarethat spiral conveyers are not new and that various means have been usedfor forcing lubricants to the hearings to be lubricated, so I do notbroadly claim such,

but

means arranged in said shaft for forcing oil' fr(1 m said oil-chamberthrough said channe 5.

2. Oiling means comprising a basehaving an oil-chamber therein, anupright stationary shaft passing through said chamber, said shaft havingan axial bore and a lateral channel communicating with said bore and.chamber, an element rotatably mounted on said shaft and a spiralconveyer arranged in said bore and operated by said rotatable element.

3. Oiling means -comprising a base having an oil-chamber therein, anupright shaft fixed on said. base,.said shaft having an oilchanneltherein extending .to the upper end of said shaft and having a lateralchannel communicating with said oil-chamber and said first-namedchannel, and means actu ated independently of said shaft for forcing oilfrom said chamber through said channels to the upper end of said shaft.

In testimony whereof I aflix my signature in the presence of twowitnesses.

JOHN w. BLOCK.
